Microservices Architecture

Microservices architecture is an approach to building an application as a collection of small, modular services that communicate over APIs. Each microservice focuses on completing one specific business capability and is developed and deployed independently.

Some key characteristics of microservices architecture include:

• Services are organized around business capabilities, so each service is responsible for a single purpose or function. For example, a microservices architecture for an e-commerce site might consist of separate services for the product catalog, user authentication, payment processing, etc.

• Services are loosely coupled, meaning they have minimal dependencies on each other. This allows for independent development, testing, and deployment of each service.

• Services communicate via APIs, often REST APIs using lightweight protocols like HTTP. This allows services built with different technologies to communicate.

• Services can be deployed independently, which enables continuous delivery and deployment of individual services.

• Services are organized around business domains, not technology layers. A service contains its own data model, user interface, and business logic.

• Services can be implemented using different programming languages, databases, and software environments, allowing teams to choose the best tools for each service.

Some benefits of microservices architecture include scalability, ease of maintenance, flexibility to adopt new technologies, and enabling continuous delivery and deployment. The tradeoffs include increased complexity in distributing services and managing cross-service dependencies.
